MALIGNANT TUMORS OF THE SMALL INTESTINE: CLINICAL OBSERVATION

The article presents classification of malignant tumors of the small intestine (MTSI) - rare tumors of the gastrointestinal tract. The approaches to diagnosis of MTSI, especially difficult at early stages of the disease, are discussed. The clinical observation of 55 years old patient with complains of nausea, abdominal pain for a long period, and signs of progressive anemia is described. In-depth examination of the patient has revealed moderately differentiated adenocarcinoma of the small intestine, T4N1M1. The enterectomy was performed. During operation, metastases in the mesenteric lymph nodes and left lobe of the liver, and ascites were detected. The patient was referred to the oncologist to decide the issue of advisability of radiation therapy or chemotherapy. It is emphasized that diagnosis was suspected in routine X-ray examination at hospital stage, and this examination could be performed in outpatient settings. The "unexplained" iron-deficiency anemia requires differential exclusion of any disease of the small intestine, even in absence of malabsorption syndrome.
